T o all, whom it may concern:

Be it known that I, ALEXANDER H. Flam', a citizen of the Unitedl Statesof America., residing at Cananea, Mexico, have'invented new and usefulImprovements in Steam- Turbines, of which the following is aspecific-ation.

This invention relates to steam turbines, the object in view being toprovide an exceedingly simple and effective motor o f the classdescribed, embodying a novel construction and form of rotor which willgreatly facilitate the manufacture of the rotor, and

any subsequent repair that may be needed thereto.

With the above and other objects in view,

the invention consists in the construction, combination and arrangementof parts, as will be hereinafter more fully described, illustrated inthe accompanying drawings, and pointed out in the' claims hereuntoappeded.

In the drawings: Figure 1 is a front elevation of a'steam turbine,embodying theA present invention. Fig. 2 is a vertical crosssection'through the same. Fig. --3 is a view in elevationV of the rotor,showing the arrangement of steam tubes and ports. Fig. 4 is an end viewof the rotor.

The main feature of the present invention resides in the f o'rm andconstruction of the rotor, which, as illustrated in the drawings,comprises a. substantially cylindrical body 1 provided about centrallythereof or at any suitable point intermediate its ends with an annularHange 2, extending circumferentially around the body, and of a suitabledepth to accommodate one or more layers of steam tubes, as shown in Fig.4. The flange 2 is provided with steam inlet ports 3 arranged in acircular series, extending entirely around the periphery of the ange 2,and communicating with the ports 3, as shown in Fig. 3, are twolaterally arranged series of steam tubes 4 which lead from the ports 3outwardly toward the opposite ends of the' rotor, and are disposedsubstantially in a spiral relation to the rotor, said tubes terminatingat or near the extreme ends of the rotor, as indicated in said Fig. 3.

Encircling the ange 2 is a steam ring 5 which is provided with a steaminlet port 6,'

with Which ll of the ports 3 register, during the revo ution of therotor. This steam ring serves to close all of the remaining ports 3, andthereby admit steam toonlyj and serve to .ing with said ports one of theports at a time, the steam passing thence through the tubesv4and-.escaping from the opposite ends thereof, but inthe meantimetraversing a substantially spiral course, which serves to give therequisite pull on the rotor- I A'casing 7 of suitable constructionsurrounds and incloses the rotor, and carries a plurality of bindingscrews 8, the inner ends of which impinge against the steam ring hold'the latter stationary and 1n proper relation'to the flange 2 of' therotor, thereby preventing the steam fromv escaping. The rotor isqnountedfast upon a central shaft 9 which has bearings in the end Walls or heads10 and 11 of the casing. Said shaft may be mounted in bearing standards12 connected to a suitablebasel which also supports the casing of theturbine.

As the steam under pressure escapes from thc spirally arranged tubes, itimpinges against the heads or end walls of the casing, and a rapidrevolution is thereby imparted to the rotor. Y The power generated bythe 'turbine may be belted orot-herwise transmitted off from the shaft9.

What is claimed is: i

1. In a steam turbine, a rotor comprising a cylindrical body, an annularHarige extending circumferentially around the body inl termediate theends thereof and provided with steam inlet ports in its peripheralface,

and steam tubes communicating with said ports and extending therefromaround the end portions of the body ina substantially spiral direction.

2. In a steam turbine, a rotorcomprising a cylindrical body, an annularfiange extend ing circumferentially around the body and provided withsteam iniet ports in its peripheral face, and tim tubes communicatnidextending therefrom around the body 'in a substantially spiraldirection.

3. In a steam turbine, a rotor comprising a cylindrical body, an annularfiange extending circumfe ent-iaily around the body intermediate the ndsthereof and provided with.'

steam inlet ports in its peripheral face, al

steam ring encircling said .tiange and provided with an inlet port, andsteam tubes communicating with said ports and extending il ..cni aroundwe portions of the bodyv in a substantiaily spiral direction'.

4. In a steam turbine, a rotor comprising a cylindrical' body, anannuiar ange extending circumferentiully 'around the body intermediatethe ends thereof and provided with steam inlet ports in its peripheralfacera Stefan ring encircling Said iange and pro-l vided with an inletport, steam tubes coin inunicating with said ports and .extending'therefrom around the end portions of the body in a substantially spiraldineetion, and a easing inelosing therotor sind'y provided with steaminlet and exhaust ports. d

5. In steam turbine? a, rotor comprising va` cylindrical body, :inannular ange extending cireuniferentially around the body and.

provided with steamvinlet ports ini its peripheral face, steam tubescommunicating with seid ports and extending therefromV around the bodyin arsubstantially spiral direction, and a Stationary steam ringencircling said Harige and 'provided with an inlet port. y l
